To use it, create a new Google Analytics property ID for your GitHub project,
head over to http://githalytics.com/ and complete the web form. You’ll be
provided a Markdown snippet to
insert in your projects README.md. It will look something like this:

Add the snippet to README.md and push the changes. When someone visits your
GitHub project page, the visit will be tracked. Great!

However, we write all our documentation using
reStructuredText. But after a
quick Twitter and email exchange with Dimitrios from githalytics and I had
a reStructuredText snippet. It looks something like this:

Same drill, except add this snippet to README.rst and push the changes.

So there you have it, Google Analytics tracking of your GitHub project landing
page. If you have more than one project, create a Google Analytics property ID
and githalytics tracking snippet for each project.
